Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following embodiments, which are to be understood as illustrative and not restrictive.
Fig. 1 is a perspective view of a cone beam projection computed tomography apparatus (CBCT apparatus) according to an embodiment of the present invention. The CBCT apparatus may support three types of modes, i.e., 3D/panoramic/CEPH modes, in which a patient is located at the same position.
Specifically, the column 1 of the CBCT apparatus can be lifted and lowered. The swing arm 2 is rotatably disposed at the top of the column 1. A rotating unit 3 is suspended at the front end of the swing arm 2, the rotating unit 3 can rotate around the self rotating center, and the rotating unit 3 can slide back and forth along the swing arm 2. The CT-bulb 4 generates X-rays for 3D/panoramic scanning. The detector 5 is for receiving signals. The CT bulb 4 and the detector 5 are respectively fixed at two ends of the rotating unit 3 and can move along with the rotating unit 3. The positioning system 6 is fixed on the middle upper part of the column 1, and the positioning system 6 is an independent part and is not connected with the rotating unit. The positioning system 6 is separated from the rotary unit 3, i.e. not in contact with the rotary unit 3, so that the movement of the rotary unit is prevented from affecting the positioning system. The CEPH bulb 7 generates X-rays for CEPH scanning, and is fixed to the upper part of the column 1 by an arm 8.
The positioning system 6 is constructed as shown in fig. 2. The positioning system 6 comprises ear rods 9, a nasion support 10, a bite block 11 and a mandible support 12. Wherein the mandibular rest 12 is used to support the mandible, the bite block 11 is used to separate the upper and lower teeth, the nasion support 10 is used to position the nasion and provide head support, and the ear stems 9 are used to position the patient's ear holes during CEPH scanning or provide head support in 3D/PAN mode. The ear rods 9 are symmetrically arranged on two sides of the head of the patient, and the ear rods on the two sides can move in opposite directions, so that the head of the patient is clamped. The base of the nasion holder 10 has a rotary joint so that it can be rotated to avoid the scanning area when necessary. Since the region in the height direction of the head of the patient is a scanning region and cannot be supported by a material having high attenuation to X-rays, such as metal, the upper positioning unit 13 is supported by the support rod 14 made of a carbon fiber material having low attenuation to X-rays and high rigidity. That is, the upper positioning unit 13 including the ear bar 9 and the nasion holder 10 is supported by a support bar 14 made of a carbon fiber material. The upper positioning unit 13 may rotate clockwise by 90 degrees from the start position (face forward) to face in the left direction, and may stop at these two positions. The handle 15 is used for the patient to hold with his hand to ensure the stability of the upper body.
FIG. 3 is a perspective view of a positioning system of the CBCT apparatus in a 3D/panoramic mode. In the 3D/panoramic mode, the patient may place his head on the mandible support 12, as shown in figure 3. While the head of the patient is fixed with the ear stems 9 and the nasion holder 10. In the 3D/PAN mode, the rotation unit 3 rotates around the head of the patient according to a preset track through the linkage of the swing arm 2 and the rotation unit 3, and meanwhile, the CT bulb 4 and the detector 5 fixed on the rotation unit 3 rotate along with the rotation unit 3, so that the scanning of 3D and PAN is realized, and at the moment, the positioning parts, namely the mandible support 12, the ear rods 9 and the nasion support 10, fix the head of the patient and keep still.
Fig. 4 is a perspective view of a positioning system of the CBCT apparatus in the CEPH mode. In the CEPH mode, as shown in fig. 4, the mandibular support 12 and bite block 11 are removed and the patient's head is secured with the ear stems 9 and nasal support 10. In the CEPH mode, X-rays are emitted by controlling the CEPH bulb tube 7 and the head side of the patient is rotationally swept. The CEPH bulb is hung at the end of the column and is connected by a rotatable joint rotating around a vertical axis, namely the CEPH bulb can rotate around the vertical axis of the rotating joint; and simultaneously, the combined motion of the swing arm and the rotating unit is controlled to ensure that the rays emitted by the CEPH bulb tube are just projected onto the detector 5 on the rotating unit 3, so that the CEPH scanning of the head of the patient is realized. In actual use, the skull correction is generally used for a few times, and the positioning device also provides the function of skull correction. Because the patient needs to rotate 90 degrees when the skull is in the right position, the three scans of 3D/PAN/CEPH can not be scanned together and need to be positioned separately. The specific positioning method for cranial correction is as follows.
Fig. 5 is a perspective view of a positioning system of the CBCT apparatus in cranial orthoposition mode. As shown in fig. 5, in the cranial positioning (CEPH PA) mode, the upper positioning unit 13 is rotated clockwise by 90 degrees to face in the left direction. The patient stands with orientation to the left. The ear pin on both sides of the ear rod 9 is used to position the ear hole of the patient. The nose pads are now rotated 90 degrees clockwise to avoid the scan area. In cranial orthopaedy mode, the CEPH bulb 7 and the detector 5 move as though they were in cranial position. Cranial orthopaedics is used to acquire a frontal projection view of the patient's head, while lateral cranial positions are used to acquire a lateral projection view of the patient. In fact, the skull correction is rarely used, so the utility model mainly realizes the one-time positioning of the skull side position, but has the function of skull correction.
The patient can be positioned at the same position in three modes of 3D/panorama/cranial position, and 3D/panorama/CEPH three-mode imaging can be obtained only by positioning the patient once, so that time can be saved when several imaging modes are required to be obtained.
The present invention may be embodied in several forms without departing from the spirit of the essential characteristics thereof, and the embodiments are therefore to be considered in all respects as illustrative and not restrictive, since the scope of the invention is defined by the appended claims rather than by the description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
